Hey John,
Please paste a full UNALTERED sip trace into a gist (gist.github.com)
from the proxy servers perspective and provide a link so that we can see
what comes in, and what goes out from both sides.
EG: ngrep -qtd any -W byline port 5060
This will show us the traffic that is leaving the proxy destined for the
Freeswitch box, and what the freeswitch box sends back.
Also - you can look in your browsers console log and provide the SIP
trace from there in a seperate gist, so that we can see what opensips
sends back up to your browser.

Am I using correct sip.js example? I copied it to my server and
accessing it using https: (used letsencrypt)

1. I would suggest using SIP.js - https://github.com/onsip/SIP.js
it is a much more active project that sipml5.
2. Im guessing that you are not properly passing flags to
RTPEngine. If you want to have DTLS-SRTP between the browser, and
plain RTP/AVP between RTPEngine and freeswitch, you need to
"offer" rtp/avp to freeswitch, and "answer" dtls-srtp back up to
the browser.
the offer to freeswitch would be:
$var(rtpengine_flags) = "RTP/AVP replace-session-connection
replace-origin ICE=remove";
and the answer back up to the browswer would be:
$var(rtpengine_flags) = "UDP/TLS/RTP/SAVPF ICE=force";

I am following
http://www.opensips.org/Documentation/Tutorials-WebSocket-2-2 and
trying to test a call
sipml5 ----------->Opensips + rtpengine --------> SIP end point
(Freeswitch)
But I do not have any audio on both sides. I see this error at
rtpengine log "SRTP output wanted, but no crypto suite was
negotiated"
Anyone tested this scenario positive?
